Note: This procedure requires assistance to torque the tie rods to the proper specifications.
Note: Clean all parts and inspect all parts. If any parts are worn or damaged, use new Caterpillar parts for replacement.
- Apply Tooling (D) onto the threads and the contact surface of each tie rod nut (7) . Place the nuts into position in the head. Ensure that the arrow on the nut is pointing upward.
Note: The tie rod and tie rod nuts are matched pairs. Each part is numbered. The front head is also numbered. The numbers for each component must match when you install the control valve.

- Tighten the tie rods in sequence to the second torque value. Refer to Table 4 for the second torque value. Refer to Illustration 4 for the proper sequence for tightening the tie rods.
- Tighten the tie rods in sequence to the third torque value. Refer to Table 4 for the third torque value. Refer to Illustration 4 for the proper sequence for tightening the tie rods.
- Tighten the tie rods in sequence to the final torque value. Refer to Table 4 for the final torque value. Refer to Illustration 4 for the proper sequence for tightening the tie rods. Heat the exposed center portions of the tie rods with a propane flame or equivalent to 275° ± 25°C (527° ± 45°F). Perform this process to obtain the turning angles of the tie rod. Use Tooling (A) to determine the temperature of the tie rods.

Note: Direct the flame away from the cylinder of the hammer. Thin steel sheets can be placed behind the tie rods in order to assist in deflecting the flame from the cylinder. Do not heat in one spot. Do not heat tie rods to a temperature that is greater than 300 °C (572 °F).
Note: The tie rods must be heated in the proper sequence.
Note: Use two people to maintain the heat on the tie rod.
- Allow the tie rods to cool.
- Install O-ring seal (5) onto plug (4) on the seal carrier.

- Install lock plates (2) onto tie rods (3) .
Illustration 9 | g00702474 |
Note: After achieving the final torque setting on the tie rods, check that the lock plates will fit before the tie rods cool. The lock plates are not symmetrical. If the lock plates will not fit, turn over the lock plate and try to fit the lock plate again. If the lock plates still do not fit, turn the tie rods slightly while heating the exposed portion of the tie rods until the lock plates can be installed.
- Install rubber rings (1) .
End By:
- Install the accumulator. Refer to the Disassembly and Assembly, "Hydraulic Accumulator - Install".
- Install the hammer into the housing. Refer to Disassembly and Assembly, "Hydraulic Hammer - Install".
